What is a Conditional Clause?

A conditional clause is a type of subordinate clause, most commonly introduced by the conjunction ‘if’ or ‘unless’. It states a condition for the main clause to be true.

Like most subordinate clauses, the conditional clause can either go before the main clause or after it. When it comes first, it's usually separated by a comma.

The Three Main Conditionals

Conditional sentences have different structures depending on whether the situation is likely, unlikely, or impossible. Learn these structures and verb forms carefully.

Base Example: If I have enough money (conditional clause), I will go to Japan (main clause).

---

Type 1 (Probable): If I have enough money, I will go to Japan.

Type 2 (Hypothetical / Subjunctive): If I had enough money, I would go to Japan.

Type 3 (Impossible Past): If I had had enough money, I would have gone to Japan.
